13 Claims. (Cl. 91-625) 1 This invention relates to new, and usefulimprovements in paint applicators and the primary object of the presentinvention is to provide a roller including means operatively connectingthe latter to a source of fluid toregulatfe a flow of fluid to, theroller so that the latter may be used to paint surfaces without thenecessit'yof placing the latter into a paint container.

Another important object of the present invention is to provide a paintapplicator embodying novel and improved valve means for con- Referringnow to the drawings in detail, and more particularly to Figures 1-6inclusive, wherein there is disclosed a preferred embodiment of thepresent invention, the n eral l0 represents ia shank provided with a sbstantially U-shaped integral extension 12 at one end. Journalled on thefree end of this extension is a roller l4 com prising a cylindricalcore'l6 and an absorbent sleeve I8 secured to the outer periphery'of thetrolling a flow of fluid from a source to the roller mechanism. I

A still further object of the present invention is to provide a paintapplicator including a feed.

chamber so designed as to permit the same to be quickly and readilyemptied or cleaned.

A still further aim of the present invention is to provide a paintapplicator that is simple and practical in construction, strongandefllcient in use, neat and attractive in appearance, relativelyinexpensive to manufacture, and otherwise well adapted for the purposesfor which the same isv intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which: I

' Figure 2 is a side elevatlonal view of Figure 1, and with parts brokenaway and shown in section;

Figure 6 is a transverse vertical sectional view taken substantially onthe plane of section line 6-6 of Figure 2;

Figure 7 is a fragmentary longitudinal vertical sectional view showingthe valve means for the core. At the opposite end .of the shank isprovidedahandle 2|).v

Adjustably embracing a portion of the roller 14, is an arcuate,transverse a shield 22 having end flanges 24. This shieldis providedwith a transverse. aperture 26 that 'co mmunicates with an aperture 28ina casing 30 and further comrnu'ni cates with the outlet opening 32 in ahollow feed chamber 34. It is preferred, that the shield, casing andfeed chamber be integrally formed.

However, the elements may be separate parts suitably secured to eachother without deviating from the scope of the present invention}.

Fixedly secured to substantially the center of chamber 34, is one end ofa substantially cylin drical valve housing 36 that communicates with oneend of an angular feed tube or fluid conduit 38.

Receivably engaging the free openend'of' the housing 36, is a packinggland 40 in which is slidably'mounted a needle valve '42. v The innerend 44' of the valve'42 is preferably pointed to engage a conical boreor seat 46 provided in the fixed end of thehousing communicating withchamber 34.

Pivotally' mounted as at 48 on the conduit 36 is the bifurcated end 49of' a lever or trigger 50. This lever is removably secured adjacent itsfree end to valve 42. The outer free end of the lever is disposed at aconvenient location relative to the handle 20. A transverse recess 52 isprovided in the upper portion of casing 30 and receives "a transversebar 54 substantially trapezoidal in cross-section,- that is pivotallymounted on pins 56 carried by the casing. This bar 54 constitutes avalve for controlling opening 26 in the shield. Spring arms 58 carriedby the casing 30 bear upon the outer face of bar 54 to normally retainthe same in a positon for closing opening 26.

In practical use of the device, the conduit 38 is coupled to theoutlet'line 60 leading from a source of fluid such as a paint pressuretank or the like (not shown). When the lever 50 is pulled by a fingertoward the handle 20, the pointed end of the needle valve is disengagedfrom its normal tight fitted position in seat 46 to permit a flow offluid into chamber 34. As'the pressure of amass:

- through openings 28 and 2 to enga e the absorbent sleeve ll 01' theroller. When lever II is released, spring 2 embracing the needle valveand biased between the packing gland ll and a retaining ring 64 mountedon the needle valve. will carry the pointed end 44 of the needle valveagain into seat 46, preventing a flow oi fluid into the chamber 34.

It should be noted, that the housing 3! and the conduit 38 are retainedor supported in position totheshank lllbyuseoipairsofarms removablysecured to each other and having their arcuate terminal portions 68formed to embrace the periphery of the shank, the conduit and the valvehousing. These arms may be adjusted for positioning of the shieldrelative to roller ll.

For the purpose of removing any fluid remaining in the chamber 34 andfor cleaning the inner surface of the chamber 34, there are providednipples II at each end 01 the chamber that receivably engage closure cap12.

Reference is now directed to Figures 7 and 8. wherein there is discloseda valve means for 'controlling opening 26 in the shield 22 in slightlymodined form. In this embodiment, a transverse groove or channel 14 is.provided in the inner periphery of the casing 30 and engages theenlarged edge or beading 16 of a plate 18 constituting a valve withinthe opening 28 of'the casing for regulating opening 26 in the shield.The ends of the plate 18 are pivoted to the ends of the casing by a pmor tne like 80 on which is fixedly secured oneend 01! a link 82; Thefree end of the link a2 is connected to a coil spring 84 carried by theouter face of chamber 34 to normally retain the plate in a closedposition relative to opening 26. This plate is so designed as to beactuated or pivoted forwardly as the fluid passes from the chamber tocontact the same. However, the plate will not allow fluid to pass fromthe shield into the chamber.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of theconstruction, operation and advantages of the device will be quiteapparent to those skilled in this art. A more detailed description isaccordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and the scope of the appended claims.
